Steps to recreate;
- Create new 3D Sidescroller project, add Set Max Jump Hold Time node and set to 1.
- Open level BP, add console command node, set to t.maxFPS 10.
- Delete the floating platforms/ledges. Jump. The character’s forehead passes just above the back wall.
- Set t.maxFPS to 120. Jump. The character’s waist now reaches the visual edge of the back wall - they jumped higher.
This might not be a problem for regular scale games with tiny little hops but for a game with slightly-smaller-than-average characters and longer jump hold times, it really affects gameplay.
